SPEED-GEARING.

SPECIFICATION forming part of Letters Patent No. 651,719, dated June 12, 1900.

Application filed March 22, 1900. erial No. 9,757 (No model.)

device may be gradually increased over the normal speed of the driving-engine, thus resulting in an economy of steam or other motive agent.

I will describe a speed-gearing embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both figures.

' Figure 1 is an elevation of a gearing ems bodying my invention, and Fig. 2 is a section on the line as m of Fig. 1.

Referring to the drawings, 1 designates a main driving-shaft, having a crank 2, with which a driving-rod 3 connects, the said driving-rod 3 being designedfor connection with a steam or other engine. The shaft 1 has a bearing in a standard 4, and on this shaft is a gear-Wheel 5, meshing with a pinion 6 on a crank-shaft 7, the said crank-shaft 7 being provided with two cranks 8 9, arranged at right angles to each other, as plainly indicated in Fig. 2. Beds 10 11 connect the cranks 8 and 9 with cranks 12 and 13 on a crank-shaft 14, these cranks 12 and 13 also being arranged at right angles to each other.

Arranged on the crank-shaft 14 is a gearwheel15, meshing with a pinion 16 on a shaft 17, having cranks 18 and 19, from which connecting-rods 20 21 extend to cranks 22 23 on a crank-shaft 24, and on this crank-shaft 24 is a gear-wheel 25, meshing with a pinion 26 on a shaft 27. Arranged below the crankshafts and having hearings in the standards 4 is a power-shaft 28, upon which are mounted gear-wheels 29, 30, and 31. These lastnamed gear-wheels are adapted to rotate with 1 is rotated by an engine or other driving power motion will be impartedfrom the gearwheel 5 to the pinion 6 and thence to the gear 29, operating the shaft 28 at a certain rate of speed. Of course at this time the gears and 31 will be out of engagement with the pinions 16 and 26. Should an increase of speed of the shaft 28 be desired, the gear 30 is to be moved into engagement with the pin ion 16, while the gears 29 and 31 are out of engagement with their pinions. The motion then will be imparted from the crankshaft 7 to the crank-shaft 14, rotating the gear-wheel 15, which through the pinion 16 and gearwheel 30 will impart rotary motion to the shaft 28 at a greater speed than that first described, and this will be carried out to a still higher speed by engaging the gear-wheel 31 with the pinion 26.

By this device three separate machines may be operatedthat is, one may have a connection with. the shaft 24, another with the shaft 27, and another with the shaft 28.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- I 1. In a speed-gearing, a series of independent main crank-shafts, a gear-wheel mounted on each crank-shaft, supplemental and independent crank-shafts, connecting-rods between the cranks of opposite crank-shafts, pinions on said auxiliary crank-shafts and engaging with the gear-wheels on the firstnamed crank-shafts, a power-shaft, andgearwheels movable longitudinally on said powershaft and adapted for engagement with the pinions, substantially as specified.

2. A speed-gearing, comprising a series of crank-shafts arranged in alinement,a series of auxiliary crank shafts arranged in alinement,
